... figure 3, the block diagram for the proposed algorithm, the three methodologies used are zero mean normal cross correlation, Hausdorff distance and texture ... Lihat dokumen lengkap

... First façade planes have to be detected, what is described in Section 2. After that every façade is processed on its own to detect the windows, what is delineated in Section 3. This has three parts. The first one ... Lihat dokumen lengkap

... The proposed improved detector employs a combination of height, width, angle, colour and texture information with the aim of more comprehensively separating buildings from trees. Although cues other than texture were ... Lihat dokumen lengkap

... Some experiments where done outside of the water with a video taken by an Olympus PEN E-P1 camera with the standard zoom lens set to the extreme wide angle f=14mm. At this setting the lens shows considerable distortions ... Lihat dokumen lengkap

... close-range applications. Hence, the rotation and translation parameters can be estimated via 3D-to-2D correspondences between 3D points derived from the TLS measurements and 2D image points of the respective range ... Lihat dokumen lengkap

... In this study, intensity image was created from laser scanner data and the registration parameters were computed with keypoints extracted by SIFT method from these images.. The results w[r] ... Lihat dokumen lengkap

... For all these reasons an optimization in the image selection phase is needed. To start with, a selection based on the information derived from the approximated model is accomplished. For a specified point in the DSM, all ... Lihat dokumen lengkap

... The cameras are directly connected to a PC via a Gigabit- Ethernet adapter using their GigE vision interface. We use two CCTV optics having a different focal length of 6.1 mm and 8 mm respectively with the cameras. The ... Lihat dokumen lengkap

... In the first case, the simulation is based on single positions, no filtering is used along the driven path. The results show that the most important factor for the positioning accuracy is the number of objects in the ... Lihat dokumen lengkap

... The key idea behind our approach is to express the landmark position error ˜X=X−Xˆ the dashed arrow in the estimated camera co-ordinate frame in terms of the unknown transformation betw[r] ... Lihat dokumen lengkap

... In this work, the input data is a set of terrestrial images shot from a mobile-mapping vehicle. We also suppose that we have a 3D geometric model of the scene, segmented in areas that are ho- mogeneous in reflectance. ... Lihat dokumen lengkap

... The visibility graph allows to cut a reconstruction/texture map- ping problem into sub-problems by inputing only the images see- ing a scene element well enough. A trivial approach to process an entire scene sequentially ... Lihat dokumen lengkap

... In this study, the optimal features are essentially spectral or tem- poral. Textural features should give better results on panchro- matic images with a spatial resolution of 2m. Indeed, the rela- tively low spatial ... Lihat dokumen lengkap

... 3.2 Mixed classes and intra-class radiometric variations Building objects can appear very different from each other on the image, since they are not covered by the same roofing ma- terial. Thus, they can not be described ... Lihat dokumen lengkap

... r is the position vector of point i and r is the mean position (centroid) for the cluster. The covariance matrix is a 3x3, real, positive, semi-definite matrix, the eigenvalues of which are always greater than or equal ... Lihat dokumen lengkap

... In general the typification algorithms developed work through the following sequence of steps: detecting groups of elements showing a pattern in their spatial distribution (e.g. parallelism, alignment, grid layout), ... Lihat dokumen lengkap

... crowds. They obtained scale invariant and good results in ter- restrial images. Unfortunately, these images do not enable mon- itoring large events, and different crowd samples should be de- tected before hand to train ... Lihat dokumen lengkap

... In this paper, vehicles were detected from the image-sequence stabilized on the road area as recorded by a hovering helicopter. It turns out to be possible to extract vehicles, as blobs, in several difficult situations. ... Lihat dokumen lengkap

... Most modern LiDAR system have the capability to acquire full waveform LiDAR data besides the discrete returns with intensity data. Waveform data is quite useful to distinguish tree species or provide better biomass ... Lihat dokumen lengkap
